2 Claims.

r be applied over the sole of a shoe and provided with means to resist slipping whereby the attachment is especially adapted for'use in connection with golfing, hiking and walking on icy "or slippery surfaces. r I

Itis. also an object of the invention to provide a device of this kind which can be applied or removed with but little effort and wherein a means of attachment is provided which will readily allow the device to adjust itself to any shape of shoe.

A further object of the invention is to provide a device of this kind provided with means whereby the front portion of the applied device is effectively held irrespective of which way the foot is twisted and wherein only one adjustable clamp is provided.

An additional object of the invention is to provide a device of this kind comprising a plate adapted to be disposed over the sole of a shoe and which plate carries means for holding the plate in place. i

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved attachment for shoes whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of our invention will hereinafter be definitely claimed.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure 1 is a view in perspective of a shoe attachment constructed in accordance with an embodiment of our invention and unapplied;

Figure 2 is a view in perspective of the adjustable clamp as herein employed;

Figure 3 is a longitudinal sectional View taken through the clamp as illustrated in Figure 2 with the associated sole plate shown in fragment;

As disclosed in the accompanying drawing, I denotes a plate of relatively thin metal or other effective material possessing a certain degree of inherent resiliency whereby such plate I when applied over the sole of a shoe will'readily bend with the foot yet possessing sufficient strength to effectively hold the calks 2 or the like project- 1934, Serial No. 747,618

'ing from the outer face thereof at desired points thereon;

The front or toe portion of the plate I is provided with transversely spaced outstanding lugs 3 with which are pivotally connected, as at 4, the toe clamping or engaging members 5. These members 5 engage over the sole of the shoe at the toe part thereof. Extending from the inner end portion of the plate I from oneside thereof is a fixed clamp or engaging member 6 which coacts with that part of the edge of the sole of the shoe'that is under the instep portion thereof. In substantially transverse alignment with the fixed clamp 6 and at the opposite side of the plate 4 is pivotally connected, as at I, an end portion of an elongated threaded member 8 which threads within an elongated tubular member 9. The member 9 is disposed from without through the adjustable clamp or engaging member Ill. The outer portion of the member 9 is enlarged and provides a shoulder I I for coaction with a shoulder I2 within the opening M of the clamp or member ID through which the member 9 is directed. The member 9 terminates outwardly of the member Ill and said extended portion of the member 9 has engaged therewith a rigid loop or key I5 whereby the member 9 may be rotated to adjust the same lengthwise of the shoulder 8 to properly set the clamp or member ID with respect to the sole of the shoe or to release said clamp or member II! from such sole.

The pivotal mounting of the clamp or engaging members 4 permits the same to readily adjust themselves to any shape of shoe and will hold the front or toe portion of the plate I in applied position no matter which way the foot is twisted.

The clamp or member 6 as is clearly illustrated in Figure 1 of the drawing is integral with the plate I and requires no adjustment. In fact, in the applying of the device and with the desired maintenance af the attachment in place it is only necessary to adjust the clamp or member l6 and after desired adjustment of the clamp or member I!) has been effected the loop or key I5 can be readily swung up close to the member or clamp I0 and out of the way. The bottom leg l6 of the clamp or member I0 is preferably tapered from above toward its outer or free end portion and said upper tapering face a is provided therealong with a groove or channel I! .to accommodate the member 9 and the exposed portion of the shank 8. The particular formation of the leg l6 of the clamp or member II) also facilitates the desired engagement of such clamp or member with the sole of the shoe because as the member l6 moves inwardly of the plate I upon requisite rotation of the member 9 the leg I6 will have a camming engagement with the plate I, thus drawing the clamp or member i8 down tight upon the sole. It is believed to be clearly apparent from the foregoing that our improved attachment embodies only one simple adjustment to effect its application or removal and that there are no parts under the foot that can be damaged or add bulk.

From the foregoing description it is thought to be obvious that an attachment for shoes constructed in accordance with our invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that our invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and'formation of the several parts herein shown in carrying out our invention in practice except as hereinafter claimed.

We claim:- r 1 1. A non-slip attachment for a shoe comprising a calked plate for application to the bottom of the shoe sole, transversely spaced members pivotally connected with the toe portion of the plate for engagement with the edge portions of the sole, a rigid member carried by the rear portion of the plate for engagement with an edge portion of the sole, an elongated member pivotally connected with the rear portion of the plate at the side portion thereof remote from the fixed member, a second elongated member in threaded engagement with the first named elongated member, a clamp member for engagement with an edge portion of the shoe sole, said second elon gated member being directed through said clamp member, said second member having means c0- acting with the clamp member whereupon said clamp member will be adjusted into engagement with the shoe sole upon rotation of said second elongated member.

2. A non-slip attachment for a shoe comprising a calked plate for application to the bottom of the shoe sole, transversely spaced members carried by the toe portion of the plate for engagement with the edge portions of the sole, a rigid member carried by the rear portion of the plate for engagement with an edge portion of the sole, an elongated member pivotally connected with the rear portion of the plate at the side portion thereof remote from the fixed member, a second elongated member in threaded engagement with the first named elongated member, a clamp member for engagement with an edge portion of the shoe sole, said second elongated member being directed through said clamp member, said second member having means ccacting with the clamp member whereupon said clamp member will be adjusted into engagement with the shoe sole upon rotation of said second elongated member.
